VENTILATOR HAT FOR STOVES Filed April 17, 1930 H. MTKH.

Patented Sept. 29, 1931 UNITED STATES ALBERT NITKA, OF MILWAUKEE,WISCONSIN VENTILATOR HAT FOR STOVES Application filed April 17,

My invention refers to ventilators and is particularly designed for usein connection with cook stoves, or the like.

The object of this invention is to provide in connection with a stovehood ventilator, a motor driven fan whereby a current of air is drawn upthrough the hood and discharged to the atmosphere.

With the above object in view, the invention consists in certainpecularities of construction and combination of parts as will be fullyset forth with reference to the accompanying drawings.

In the drawings, Figure 1 represents a front elevation of a stove andventilator hood embodying the features of my invention; and

Figure 2 is a side elevation of the same with parts broken away andother parts in section to more clearly illustrate structural features.

Referring by characters to the drawings, 1 represents a standard stove,and mounted thereover is a hood 2 having conical faces upon four sideswhich merge into an opening 3 at the top for the reception of aventilator pipe 4, which pipe may enter a convenient chimney or it maybe directed through a window, or other accessible opening to theatmosphere.

The lower flanged lip 5 of the hood is, as shown, anchored to the wallby a clip 6 and the hood at its mouth end is of suflicient dimenslon toencompass the full area of the stove, whereby smoke and odors therefromwill be cleared and discharged through the ventilator pipe.

In order to create a forced draft which is sufficient at all times todraw into the hood the entire volume of smoke and odors, I providebrackets 7, which brackets extend from the inner walls of the hood nearits upper end, and resting thereupon and secured to the brackets is anelectric motor 8, having ears extending therefrom for engagement withthe bracket.

The motor shaft 9 is in axial alignment with the mouth of the ventilatorpipe and extends in parallel relation to the pipe mouth.

The end of the shaft 9 has secured thereto 1930. Serial No. 445,066.

a propellor or suction fan 10, which fan is approximately the diameterof the vent pipe and is housed directly beyond its mouth, as shown inFigure 2 of the drawings.

By this arrangement, it will be observed that the hood for ventilating acook stove and kitchen, is rendered capable of disposing of all of theodors and gases which may arise from the stove irrespective of draftconditions of the pipe 4, and all that is necessary to put the apparatusinto operation is to close a switch which will control the electriccurrent to the motor, the said wiring and switch forming no part of myinvention and not shown. It will be noted that the hood may be made upin portable form as, for example, it might constitute a part of, or beattached to the stove, in which case, the pipewould be thereafterassembled and connected to any suitable vent opening.

Inasmuch as in practice, the hood 2 must necessarily be positioned inspaced relation above the stove in order to permit suitable accessthereto, it may be desirable in some instances to provide a shield 11,which may be attached to the stove in any suitable manner and projectupwardly into close proximity to the mouth of the hood.

It will also be obvious that the sides of the shield will prevent sidedrafts from carrying odors away from the stove, and will insure the samebeing drawn into the hood.

Due to the fact that vapors and odors are discharged through the ventpipe 4L with considerable force, it has been found that were the samedelivered into a flue at an approximate right angle to the flue,considerable back pressure is built up, which interferes materially withthe draft of the flue and any other heating apparatus connectedtherewith.

It is, therefore, proposed to connect the ventilating pipe 4 with anangularly disposed communication 4 with the interior of the flue. Thus,as the vapors are discharged into the flue, the same will be directedupwardly, whereby the draft within the flue will be increased ratherthan retarded.

While I have shown and described the preferred embodiment of myinvention, it will be apparent that slight changes may be made in theconstruction when putting the invention into practice Without departingfrom the spirit of the same or the scope of the appended claim.

I claim:

A ventilator hood for stoves having a mouth adapted to be positionedover the top or" the stove and having an opening in its top Wall, a ventpipe leading from said opening, brackets extending from the inner Wallof the hood, a motor carried by the brackets, a fan associated with themotor and extending into the Vent pipe and a shield depending from thelower open side of the hood and embracing the back and sides of thestove.

In testimony that I claim the foregoing I have hereunto set my hand atMilwaukee, in the county of Milwaukee and State of Wisconsin.

ALBERT NITKA.
